Abstract: This research is done to optimize the rice husk residue usage with the production of activated carbon by using the chemical activation method consecutively after the silica extraction. The silica extracted rice husk was impregnated with different concentration of KOH solution and then burned to activation at the predetermined activation temperature to obtain the activated carbon. The optimum condition to produce the activated carbon is impregnation with 30 % concentration of KOH solution at 750 oC activation temperature. The maximum methylene blue uptake of the activated carbon produced are tested to be 322.36 mg g-1. The adsorption isotherm model study was done using Langmuir isotherm. The Langmuir isotherm adsorption capacity, Qe was calculated to be 416.67 mg g-1 while the rate of adsorption, b value was 4.8 mg-1 with R2 0.9995. The results obtained from this study show that the silica extracted rice husk is a suitable precursor for preparing an activated carbon and the activated carbon have good absorption capacity (More)
